To L'ZZ whaha/Ait midi/concern.: I *y u .Be itlmown thatl, MAUROE C. HERNAN,"a

tion, lin connection Vwith'vthe accompanying drawings, is a specification, Alike numerals on ythe drawing's'repre'senting likenvpa'rts.

, .This'invention has for its jobjecttoprovide fa novel strainerifor straining the contentsy of ,barrel s casks, tanks, &c.`, as theyT 'are drawn therefrom.

. v'1`hefdevice has been especially,I designe-didi' straining beer, wine, or similar'beverages'as they are drawn from barrels and casks, al-

fthough lthe invention fisn'ot limited `b'yany means to this particular use.y Heretofore, so far as Ija'm aware, 1t has been customary to strain beer, wine, &c., by

attaching a strainer to the discharge end of the faucet, the strainer `being entirely Outside of the barrel. kl.havefd'eiised anovelfstrainer which is adapted to be insertedwithin the barrel or Cask after the barrel has been tapped and before the faucet is inserted in place, and in accordance with my invention I have provided a collapsible strainer which can be collapsed, so as to be inserted through the hole tapped in the barrel, but which can be expanded from the exterior of the barrel after being thus inserted into the barrel and before the faucet is screwed into the hole.

In the best form of my invention now known to me the strainer, which may be of cloth or other suitable material, is placed over a foldable or collapsible frame which can be folded to be inserted in the hole tapped in the barrel and can after its insertion be expanded to stretch the strainer-cloth.

A construction embodying my invention will be hereinafter described, and the novel features of the invention will then be pointed out in the claims.

ln the drawings, Figure 1 is a section through one end of a barrel, showing my improved strainer device applied thereto. Fig. 2 is a View of the frame of the strainer device when collapsed and ready for insertion in the barrel, the strainer Vitself' being shown in section. Fig. 3 is a section of the sliding collar.

Fig. 4 is an end View of the sliding collar. Fig. 5 is an enlarged View of the sliding collar in place on the tubular stem.

V1n the embodiment of my invention herein illustrated the strainer 3, which may be of any suitable fabric or similar material, is stretched over and incloses a folding or collapsing frame. This frame may assume various shapes, the only requisite being that it lcapable ofbeing collapsed so as to be inserted through thehole tapped in the barrel, Cask, vdac., for the insertion of the faucet. The frame herein shown comprises a central tubular member 4, provided with a plurality perforations 5 and having 'pivotally con- /iiected to one endfribs 6, of resilient material, such, 'for instance, as ktempered wire. Said ribs 'are connected lto a collar 7, slidably 'mounted on'the tubular stem 4, whereby when 'the collar is moved to the left, Fig. 2, the ribs vare bowed outwardly, as shown in Fig. 1. When they coll'aris withdrawn to the right or .toward the end of the`stem, the ribs are collapsedA against the stem and lie substantially `parallel` thereto. The strainer material 3 en- ,circles this folding frame and is made fast to the collar 7 ,thereby forming a bag which incloses the ribs 6.- The stem 4 is provided with a projection 8, which normally occupies a keyway 9 in the collar 7. When the frame is expanded, however, the collar 7 is moved to the left, Fig. 1., until the projection 8 clears the end of said collar, and the frame may be locked in its expanded position by merely turning the collar so as to cause the projection 8 to engage the notch 10 therein, as seen in Fig. 1. The collar 7 is provided with eX- terior screw-threads 11, which are adapted to engage interior screw-threads in the ends of the faucet 12.

In inserting my strainer device the barrel or cask is iirst tapped, and then the folded strainer, as shown in Fig. 2, is inserted through the hole thus made, the left-hand end of the frame beinginserted first. When the strainer has been inserted through the aperture in the barrel, said frame may be expanded, as shown in Fig. 1, by moving the collar outwardly on the tubular stem 4, and when the frame is thus expanded it may be locked in the expanded position by turning the collar to cause the projection 8 to engage the notch 10. The faucet is then screwed to the bushing, after which the faucet may be screwed into the hole tapped in the cask or barrel, all as usual. It will thus be seen that my improved strainer is situated entirely within the barrel and may be inserted in the barrel at the time the latter of a faucet, said frame being eXpandible from is tapped and may also be removed from the barrel when the latter is empty.

My invention is not limited to the particular construction of folding frame herein shown, as I believe I am the first to devise any kind of a folding or collapsible strainer adapted to be inserted through the hole tapped in a barrel or Cask prior to the application of the faucet to such hole, and therefore I desire to claim, broadly, a folding strainer adapted to be thus inserted.

I consider the construction herein illustrated as a practical one; but it will be obvious that many changes in the construction of the folding frame may be made without departing from the invention.-

Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. A collapsible strainer adapted to be inserted into the hole tapped in a barrel, cask or tank for the reception of a faucet, and means to expand said strainer from outside the barrel, Cask or tank after it is thus inserted.

2. A collapsible strainer adapted to be inserted into the hole tapped in a barrel, cask or tank for the reception of a faucet, means to expand said strainer from outside the barrel, cask or tank after it is thus inserted, and means to attach said strainer to a faucet.

3. In a device of the class described, a strainer comprising a folding frame adapt-ed when folded to be inserted in the hole tapped in a barrel, cask, tank, &c., for the reception the outside of the barrel, cask, &c., after being thus inserted, and a strainer inclosing the frame.

4. In a device of the class described, a strainer comprising a folding frame adapted when folded to be inserted in the hole tapped in a barrel, cask, tank, 85e., for the reception of a faucet, said frame being expandible from the outside of the barrel, cask, &c., after being thus inserted, and a strainer inclosing the frame, said frame having means for attachment to -a faucet.

5. In a strainer, a perforated tubular stem, a collar slidably mounted thereon, resilient ribs secured at one end to said collar, and at the other end to the stem, whereby movement of the collar on the stem expands the ribs, and a strainer inclosing said ribs.

6. In a strainer, a perforated tubular stem, a collar slidably mounted thereon, resilient ribs secured at one end to said collar, and at the other end to the stem, whereby movement of the collar on the stem expands the ribs, and a strainer inclosing said ribs, said collar being eXteriorly screw-threaded for attachment to a faucet. I

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
